One of Eleuthera's Most Popular Attractions
Referred to as the narrowest place on Earth
The Glass Window Bridge is located just North of Gregory Town on the Northern end of Eleuthera Island. This wild, romantic rock formation separates The Atlantic Ocean to the right from the Sound, visible under the Bridge and extending to the west of Eleuthera. The man-made bridge took the place of a naturally formed bridge of rock that was destroyed in a hurricane. From the bridge, you can see a phenomenal contrast between the dark blue Atlantic Ocean churning away and the calm turqoise waters of Caribbean Sea. The colors are truly amazing. 
Eleuthera, an island 110 miles long, narrows at Glass Window to an isthmus only as wide as the bridge itself. On the eastern, Atlantic side the highway is flanked by ridges leading up to cliff tops 80 feet above the ocean. The approach is thus blind on this side, until you actually reach the bridge where the deep blue Atlantic heaves into view. On the western, Caribbean side the view of the emerald-green Bight of Eleuthera is expansive. You can see for miles. Seemingly harmless, the bridge at Glass Window is deadly. Take a look at our photo gallery of the Glass Window Bridge to see it from different locations. There is also a drone video of the Glass Window Bridge in our video catalog.
Owing to the high cliffs that narrow into a recess at this pass, Glass Window is susceptible to what Bahamians call rages--enormous waves from the Atlantic side, some reaching heights of 100 feet, driven up as they enter the narrow, high concave of cliffs. Spawned by storms far out at sea, these tsunami waves explode into the bridge even on days when the sky above Eleuthera is clear and blue. The weather provides no warning of what may be happening at Glass Window.
The force of these rogue waves is tremendous. When Winslow Homer painted Glass Window in the nineteenth century, a rock ledge topped the structure, creating the impression of a natural window. It has long since been destroyed. The succession ofhighway bridges that replaced the ledge have fared no better.

A rage on Halloween day 1991 knocked the present bridge 11 feet closer to the Bight of Eleuthera. Boulders the size of Airsteam trailers heaved up by rages litter the cliff tops near Glass Window, stark testimony to the power of rages.
You should take great care when visiting the Glass Window Bridge and the surrounding cliff areas. Rogue waves have been known to arrive unexpectedly and wash over the bridge and nearby cliffs. Since there are no immediate reefs along the ocean side to break up these rogue waves as they arrive, the waves can hit with great force and have been known to not only wash people out into the ocean, but vehicles as well. Again, please be cautious when visiting Eleuthera's Glass Window Bridge, and by all means, don't forget to bring your camera.
